Title: High-speed reproducing method of magnetic recording and reproducing device
Inventor: NISHIJIMA HIDEO
IPC: H04N5/783
Filed: 1981-10-30
Abstract: PURPOSE:To obtain an excellent high-speed reproducing signal free of the generation of noise by varying the angle of winding inclination of a magnetic tape around a magnetic drum during reproducing according to the feed speed of a magnetic tape. CONSTITUTION:A drum motor 5 is controlled by a driving circuit 6 to obtain a reproducing video signal of desired frequency, and the rotary phase of this magnetic drum is detected by a tack head 12. Its detecting signal and a signal obtained by detecting a control signal recorded on a magnetic tape 1 are applied to a phase comparison 13 for phase comparison. Its phase comparsion output  is applied to a driving circuit 8 to control a capstan motor 7. Consequently, magnetic tracks recorded on the magnetic tape 1 are put in phase with video  heads equipped on the magnetic drum 4 during scanning to obtain an optimum  output signal.

Title: Tuning fork type piezoelectric oscillator
Inventor: SATOU HIROCHIKA
IPC: H03H9/215
Filed: 1979-12-27
Abstract: PURPOSE:To reduce the energy of oscillation leaking outside from the tuning fork basement, by providing an elastic member having its longer direction almost vertical to the longer direction of the oscillating arm at the basement of the oscillator and in one a body with the basement. CONSTITUTION:The tuning fork type piezoelectric oscillator 21 consists of the oscillating part 22 formed by two pieces of oscillating arms and the basement 23. The elastic member 25 interlocking the contraction part 24 and the oscillating part 22, the member 26 connected across the member 25 and the support arm 27 which is supported and fixed to a supporting member are provided in a body to the basement 23. Only the Y' and Z' direction displacement component are transmitted at the part 24 for the displacement of the basement 23, and thus the member 25 is moved in a minute flexion oscillation. The size with which the member 25 resonates with the oscillating part is decided, and thus the oscillation of the oscillating part is reflected by the member 25 and not transmitted to the member 26 and the arm 27.

Title: Photomask
Inventor: HOSAKA SUMIO
IPC: G03F1/48
Filed: 1982-10-04
Abstract: PURPOSE:To protect a photomask from pollution and protect light shielding material constituting elements from pollution due to impurities and virulence, by arranging a plate-shaped member separated from a light shielding film so that this member faces a substrate with the light shielding film, which is provided for forming a pattern on a part of the substrate, between themselves and making one of the substrate and the plate-shaped member light-transmissive at least to constitute and photomask. CONSTITUTION:A laser beam 5 is made incident to a photomask blank 12 from the surface of an optical glass 1 on the side opposite to that of formation of a light shielding film 2 on this glass 1, and the light shielding film 2 is worked directly into a desired pattern by a laser describing device to form a reticle pattern. A photomask 12' formed in this manner is set as a reticle of a reduction projecting exposure device in an optically fixed position. The pattern of the photomask 12' passes through a reduction projecting lens 8 to form a reduction pattern on a sample table 9 having a wafer. Since the reticle attained by using the photomask blank 12 is covered with optical materials, the occurrence of a defective pattern on the wafer due to stucking of foreign matters is prevented at this time.

Title: Dyeing method for hard contact lens and dyed hard contact lens
Inventor: KATO YASUYUKI
IPC: G02C7/04
Filed: 1988-07-12
Abstract: PURPOSE:To enable uniform and strong marking without any well by making a sublimating dye to penetrate the surface of a lens by sublimation by using a transfer method. CONSTITUTION:The sublimating dye 6b is made to penetrate the surface of the lens 4 by sublimation by using the transfer method. An oxygen permeable hard contact lens(HCL) is larger in copolymer molecule gap than a normal HCL consisting principally of polymethyl methacrylate, etc., so the sublimating dye 6b can be made to penetrate the lens 4 relatively easily. Thus, the sublimating dye 6b is made to penetrate the surface of the lens 4 by sublimation by the transfer method to perform dyeing for marking, etc. Consequently, there is no swell of dyed part on the surface of the lens 4 and the uniform and strong marking is enabled.

Title: Jet generator using electric field
Inventor: YABE AKIRA
IPC: H02N11/00
Filed: 1988-07-12
Abstract: PURPOSE:To easily generate a jet stream by opening unequal holes in an electrode and differentiating intervals or arrangements of the holes. CONSTITUTION:A porous plate electrode 13 of a jot generating electrode is composed of a platelike electrode material 18 in which a plurality of large holes 19a and small holes 19b are alternately opened. Holes opened at the material 18 operate as a wide region W at the large hole 19a and as a narrow region S at the small hole 19b. When a high voltage is applied between the electrode 13 and a surface electrode, liquid directly under the electrode 13 is at highest pressure and the liquid of the region of the large hole 19a is lowest. Accordingly, the liquid is fed from the holes 19b between both the electrodes, and fed as jet stream from the hole 19a. Thus, the jet stream can be generated in the liquid without presenting a movable unit.

IPC: H01L21/56
Filed: 1990-06-29
Abstract: PURPOSE:To prevent disorder of flow near a gate at the initial of filling resin and to eliminate air reservoirs, voids by reducing the thickness toward an end in a resin-sealed part near the gate. CONSTITUTION:A sealing resin part 12 near a gate 5 is so formed as to gradually reduce in thickness toward its end with a gradient. The near part 71 of the gate 5 of a mold cavity 7 is gradually reduced in thickness toward the gate 5. A chain line indicates the end shape of the cavity when the thickness is not reduced. Since melted resin 6 is gradually increased in thickness at the part 71 immediately after melted resin 6 is introduced from the gate 5 in the cavity 7, no void is generated.

Title: Supporting jig for welding flux
Inventor: MATSUZAKI SEIJI
IPC: B23K37/06
Filed: 1990-06-30
Abstract: PURPOSE:To quickly support a backing material or a corner material at a prescribed position of a material to be welded by using a supporting cover having a self attractive property through magnetism detaining the backing material for welding. CONSTITUTION:An L shape or box shape plate is formed from a steel plate of temporary magnet of ferromagnetic substance such as mild steel and a permanent magnet such as ferrite magnet is arranged on the inside of it. In this way, since a supporting jig itself is magnetized into a magnet 2, it attracts a material to be welded and leakage of magnetic lines of force from the permanent magnet can be minimized. More attractive force by magnetism can be obtained than the permanent magnet alone. The supporting jig, simultaneously, has a function as a receptor of various types of flux, serves as a supporting jig for welding flux short of self-attractivity and requires no other detaining tool. In this way, when a magnet is mounted on a supporting cover made from magnetic steel, the attracting force by magnetism generated in an attracting part of the supporting cover can be made larger than when attracted by the magnet alone.

Abstract: PURPOSE:To smooth the concentration of returned sludge and the concentration of MLSS in an aerating cell, even when the amount of inflow sewage is abruptly changed, in the purification of sewage, by adding primary delay to the control of a returning ratio in an active sludge process. CONSTITUTION:The amount of inflow sewage flowing into a sewage disposal plant is measured by a flow meter 2 or the like provided in a water intake well 1. The signal of the flow rate is inputted to a primary-delayed arithmetic circuit 10, the resulting output is multiplied with a predetermined coefficient by a ratio-setting instrument 9, and the obtained flow rate is handled as a set value for the amount of returned sludge. said set value is set at a controller 8, and a valve 6 for returned sludge is operated by using its difference from a flow rate actually measured by a flow meter 7 for returned sludge as deviation. According to this system for controlling the returning ratio, the abrupt decrease of the concentration of the returned sludge derived from the abrupt increase of the amount of inflow sewage is inhibited so that the influence of disturbance on the final precipitating pool 4 can be alleviated.
